Data visualization using level of detail magnification

ABSTRACT

A visualization engine may provide, on a screen, a visual display of an object, the object being associated with object data having a data display size smaller than a visual threshold and therefore not displayed on the screen. The visualization engine may include a request handler configured to receive a magnification request to magnify the object at a magnification speed, a threshold manager configured to determine a data threshold at which fetching of the object data must be initiated to ensure receipt thereof prior to the visual threshold being reached, and an object comparator configured to initiate fetching of the object data, based on the visual threshold, the data threshold, and the magnification speed. The visualization engine may then display the object data within the object upon magnification of the object meeting the visual threshold.

TECHNICAL FIELD

This description relates to data visualization.

BACKGROUND

Conventional computing systems provide for the storage of, and accessto, large quantities of data. However, it may be difficult orinconvenient for users to locate desired data, or otherwise to interactwith such large datasets in a desired manner.

In order to facilitate user interactions with large datasets, graphicaluser interfaces have been developed which are designed to providevisualizations of the data. For example, such graphical user interfacesmay provide diagrams, charts, dashboards, or other visualizationsrepresenting data elements of a dataset, or aggregations or othercombinations thereof. In some cases, users may be provided with anability to zoom in or zoom out with respect to selected data elements,and/or to group selected subsets of data elements for collective viewingthereof.

While such systems and related techniques may be capable of providing asatisfactory user experience in certain contexts, significant room forimprovement exists in the realm of visualizing, and otherwiseinteracting with, very large datasets. Moreover, in conventional datavisualizations, the data visualizations may rely on predefined queriesand data paths, and generally provide, at best, merely a simplifiedgrouping of data elements corresponding to the predefined queries ordata paths. Consequently, in these and other contexts, a user's abilityto view and access data in a desired, flexible manner, and with aminimum of wait time or other inconvenience, may be effectively reducedor prevented.

SUMMARY

According to one general aspect, a system may include instructionsrecorded on a non-transitory computer-readable storage medium, andexecutable by at least one processor. The system may include avisualization engine configured to cause the at least one processor toprovide, on a screen, a visual display of an object, the object beingassociated with object data having a data display size smaller than avisual threshold and therefore not displayed on the screen. Thevisualization engine may include a request handler configured to receivea magnification request to magnify the object at a magnification speed,a threshold manager configured to determine a data threshold at whichfetching of the object data must be initiated to ensure receipt thereofprior to the visual threshold being reached, and an object comparatorconfigured to initiate fetching of the object data, based on the visualthreshold, the data threshold, and the magnification speed. Thevisualization engine may be configured to display the object data withinthe object upon magnification of the object meeting the visualthreshold.

According to another general aspect, a computer-implemented method forexecuting instructions stored on a non-transitory computer readablestorage medium may include providing, on a screen, a visual display ofan object, the object being associated with object data having a datadisplay size smaller than a visual threshold and therefore not displayedon the screen, and receiving a magnification request to magnify theobject at a magnification speed. The method may further includedetermining a data threshold at which fetching of the object data mustbe initiated to ensure receipt thereof prior to the visual thresholdbeing reached, initiating fetching of the object data, based on thevisual threshold, the data threshold, and the magnification speed, anddisplaying the object data within the object upon magnification of theobject meeting the visual threshold.

According to another general aspect, a computer program product may betangibly embodied on a non-transitory computer-readable storage mediumand may include instructions that, when executed by at least onecomputing device, are configured to cause at least one computing deviceto provide, on a screen, a visual display of an object, the object beingassociated with object data having a data display size smaller than avisual threshold and therefore not displayed on the screen, and receivea magnification request to magnify the object at a magnification speed.The instructions, when executed, may be further configured to cause theat least one computing device to determine a data threshold at whichfetching of the object data must be initiated to ensure receipt thereofprior to the visual threshold being reached, initiate fetching of theobject data, based on the visual threshold, the data threshold, and themagnification speed, and display the object data within the object uponmagnification of the object meeting the visual threshold.

DETAILED DESCRIPTION

FIG. 1 is a block diagram of a system 100 for data visualization usinglevel of detail magnification. In the example of FIG. 1, the system 100includes a visualization engine 102 that is configured to provide afast, convenient, intuitive, and interactive visualization of very largedatasets.

In particular, for example, the visualization engine 102 may beconfigured to provide a zooming or magnification effect which isexperienced by the user of the system 100 in a smooth, seamless manner,even for extremely large datasets. Additional detail and explanationwith regard to these example features of the visualization engine 102are illustrated and described below with respect to the exampleembodiment of the visualization engine 102 of FIG. 2, and with respectto subsequent FIGS. 3-9 and associated description thereof.

In additional or alternative examples, the visualization engine 102 maybe configured to provide visual bundlers which group and representspecified data subsets of very large datasets in a manner that isexpressive and intuitive for user of the system 100, and which providesa dynamic, configurable visualization that may be leveraged by a user ofthe system 100 to search, aggregate, or otherwise interact with the dataof a very large dataset. An example implementation of these and relatedfeatures of embodiments of the visualization engine 102 are illustratedand described below with respect to the example visualization engine ofFIG. 10, which is further described and illustrated with respect toFIGS. 11-20.

By way of context and overview, FIG. 1 illustrates that thevisualization engine 102 may be configured to interact with a database104, which may represent virtually any database capable of storingsuitably large quantities of data. In particular exampleimplementations, the database 104 may represent an in-memory database,such as the in-memory HANA database of SAP AG.

Further in FIG. 1, the visualization engine 102 is illustrated ascommunicating with a template repository 106. As described in detailbelow, the template repository 106 may be configured to store aplurality of layout templates, each layout template including variouslayout elements, so that the stored layout templates may be consideredto represent visualizations that are at least partially preconfigured,to thereby facilitate constructions of data visualizations by thevisualization engine 102.

For example, as also described in more detail below, the layouttemplates of the template repository 106 may each be described as havinga particular geometric shape, relative size, color, static content(e.g., a header or other included text), or relationship to one or moreother layout templates or types of layout templates. Meanwhile, layoutelements of a specific layout template may be defined for inclusionwithin the corresponding layout template. In particular, a layoutelement may be embedded, perhaps with one or more other layout elementor type of layout element within its corresponding layout template.Similarly, a layout template may be embedded within another layouttemplate, thereby defining a hierarchy of embedded layout templates andassociated layout elements.

Thus, the visualization engine 102 may be understood to be configured tocombine data from the database 104 with layout templates and associatedlayout elements of the template repository 106, to thereby provide adefined visualization of the selected data from the database 104. Oncesuch a visualization is defined, a rendering engine 108 may beconfigured to render the visualization within the context of a userinterface 110. Various examples of the thus-rendered visualizationswithin the user interface 110 are illustrated and described below. Ingeneral, however, it may be appreciated that the rendering engine 108may represent, by itself, virtually any conventional or otherwisesuitable rendering technology or technique, e.g., a conventionalbrowser, media player, or other technique for rendering visualizationwithin the user interface 110.

FIG. 1 also illustrates that in the example of the system 100 of FIG. 1,server hardware 112 may be utilized to implement the database 104, thetemplate repository 106 and the visualization engine 102. Meanwhile,client hardware 114 may be utilized to implement the rendering engine108 and the user interface 110. In this regard, again, it may beappreciated that the client hardware 114 and the server hardware 112, aswith the rendering engine 108, may represent otherwise-conventionalhardware and software components, which are effectively transformedthrough the use of the visualization engine 102 and the templaterepository 106, and associated hardware and/or software, into the system100 of FIG. 1. Consequently, further description of the server hardware112, the client hardware 114, and/or the rendering engine 108 is notprovided in detail herein, except as may be necessary or helpful inunderstanding operations of the system 100 of FIG. 1.

Moreover, it should be appreciated that the system 100 of FIG. 1 isintended merely as an illustrative and non-limiting example. Inalternative implementations, the visualization engine 102 may beimplemented partially or completely using the client hardware 114, whileinteracting with the database 104 and the template repository 106 by wayof suitable network connection. Various other example implementationdetails of the system 100 of FIG. 1, some of which are described below,should be considered to be within the scope of the example of FIG. 1.

FIG. 2 is a block diagram of an example implementation of avisualization engine 102A, representing an embodiment of thevisualization engine 102 of FIG. 1. As referenced above, and asdescribed in detail below, the visualization engine 102A may beconfigured to provide a level of detail magnification mechanism whichallows the visualization engine 102A to present a birds-eye viewvisualization of thousands or millions of data elements, in which thevisualization is capable of seamlessly exposing more detail as the userzooms in on a selected area of the visualization. Particularly when usedwith an in-memory database representing the database 104 of FIG. 1, thevisualization engine 102A is capable of creating an illusion that all ofthe data of the database 104 is available for immediate rendering by therendering engine 108. More particularly, a user of the visualizationengine 102A is provided with an ability to continuously drill down andexplore the visualized data, with a virtually-unlimited level of detail.

In particular example implementations, as described in more detailbelow, a visualization provided by the visualization engine 102A mayrepresent every individual data object by a corresponding visual objectthat is available for showing at the user interface 110. Then, dependingon a selected magnification level, such visual objects may be renderedas being very small (e.g., at a level of a single pixel), or very large,while transitions between these visual sizes is as seamless as opticalzooming.

The visualization engine 102A achieves these and related results, forexample, by anticipating when specific visual content of any generatedvisualization will be needed, so that data required from the database104 for the generation of the visual content is retrieved in enough timefor rendering thereof, at or before a time that the user of thevisualization engine 102A needs or wants the requested visual content.

In other words, for example, during a time when the user is requestingan increased magnification of a specified portion of visual content,where the visual content is currently being displayed at a firstvisualization level, the visualization engine 102A may effectivelyanticipate that data at a more detailed level will soon be required forvisualization thereof as a result of the current magnification request.Then, the visualization engine 102A may anticipatorily fetch some or allof the data from the database 104 that would be required for inclusionat the requested, magnified level of the visualization. Consequently,from a perspective of the user, it appears that the requestedmagnification and associated display of magnified data elements occursin a smooth, fast, and seamless manner.

As referenced above, the layout templates of the template repository 106may be instrumental in achieving these and related results. For example,embedded levels of layout templates and associated layout elements maygenerally correspond to magnification levels that may be requested bythe user. Then, when the visualization engine 102A determines that theuser is requesting magnification from a current magnification level to asubsequent magnification level, it may be necessary to retrieve datafrom the database 104 which is required for inclusion within theembedded layout template corresponding to the subsequent, requestedmagnification level.

Thus, such embedding of visual objects into visual objects,corresponding to the embedding of layout templates within layouttemplates, helps to provide for an effectively infinite level of detail,by providing an ability to recursively add visual objects for a relatedcontent, as the user zooms in with respect to a given visualization. Inother words, the visualization engine 102A may be configured to leveragethe defined layout templates of the template repository 106 to provide adynamic creation of visual objects for rendering by the rendering engine108 using the user interface 110.

The layout templates and related features facilitate such results bypre-describing a visual design of each layout template (e.g., ageometry, typography, and arrangement of each layout template), as wellas content to be visualized (e.g., attributes, or associated objects).The one or more layout elements of a particular layout template may thusdescribe, e.g., geometric shapes, text areas, or embedded visualobjects. The layout elements may be bound to static content, such ascaptions or label text, or data content of the object to be visualized(e.g., attributes or associated data objects). In particular, withrespect to the type of embedding of layout templates referenced above,layout elements may be used to describe embedded visual objects whichspecify a relation of each embedded object to a parent object within anoverall data model of a template repository 106. For example, arepresentation of a group may embed group members by referring to a “hasmember” association.

In more detail, the visualization engine 102A is illustrated asincluding a request handler 202. The request handler 202 may beunderstood to receive any suitable request from the user, e.g., by wayof the user interface 110 of FIG. 1. For example, as described in detailbelow, the request handler 202 may receive requests for specificgroupings or views of specified data of the database 104. Once aninitial visualization has been provided, as described herein, therequest handler 202 may receive a request for magnification of theprovided visualization (e.g., zooming in and/or zooming out of theprovided visualization).

Further in the example of FIG. 2, the visualization engine 102A isillustrated as including a screen size monitor 204. In this regard, itmay be appreciated that the user interface 110 may be provided withrespect to a wide range of display screens. For example, the userinterface 110 may be provided on a very large monitor or projection, oron a standard-size display screen (e.g., desktop monitor) associatedwith a desktop or laptop computer. In other examples, the user interface110 may be provided in the context of a much smaller display screen,such as a display screen of a smartphone or other mobile device. Thus,it may be appreciated that the user interface 110 may in fact beprovided on virtually any available or suitable display screen.Moreover, a user may request the same data to be displayed at differenttimes on various display screens having corresponding various screensizes.

As will be appreciated from the discussion below, the visualizationengine 102A is capable of providing the type of seamless magnificationdescribed herein, regardless of a type or nature of available displayscreen. In so doing, the visualization engine 102A may rely on screensize obtained from the screen size monitor 204. For example, the screensize monitor 204 may provide a number and configuration of individualpixels of a current display screen, along with other suitable screensize information, such as dimensions of the display screen in question.

The visualization engine 102A also includes a threshold manager 206. Thethreshold manager 206 may be configured to utilize one or morepredefined level of detail thresholds as a basis for triggeringcorresponding actions associated with a retrieval and ultimate renderingof requested data. In other words, as a magnification request isreceived from the user by way of the request handler 202, the thresholdmanager 206 determines, relative to screen size information obtainedfrom the screen size monitor 204, whether the current magnificationrequest is sufficient to initiate the actions necessary to provide thetype of seamless zooming referenced above.

In the example of FIG. 2, the threshold manager 206 is illustrated asincluding a visual threshold manager 208, a structural threshold manager210, and a data threshold manager 212. In reverse order, the datathreshold manager 212 may be configured to determine when data requiredfor creation of a corresponding layout element needs to be requestedfrom the database 104 in order to finish associated fetching of therequested data in sufficient time to allow for a subsequent constructionof the corresponding layout element, as well as for ultimate renderingof the combination of the retrieved data and associated layout element.

Thus, upon retrieval of the requested data from the database 104 inresponse to a determination of triggering of the data threshold, thestructural threshold manager 210 may proceed to assemble or otherwiseinstantiate a corresponding layout template and associated layoutelements from the template repository 106. In this regard, a templateselector 214 may be configured to select one or more appropriate layouttemplates from the template repository 106, based on, e.g., which datahas been requested by the user, and based on the specific magnificationcurrently being requested by the user.

Once necessary data has been retrieved and corresponding layouttemplates have been instantiated or otherwise constructed, the visualthreshold manager 208 may determine that the ongoing magnificationrequest has reached a point that actual rendering of thealready-obtained data and associated structure should begin to beexecuted by the rendering engine 108. In more detail, the visualthreshold manager 208 may determine a particular manner in which arequested data object is actually transformed into pixels on a currentdisplay screen, depending on a current level of magnification requestedby the user. For example, at a first level of magnification, aparticular data element may be determined to be only the size of asingle pixel, so that any included layout structure or associated datamay not be distinguishable. At a second level of magnification, the samestructure/data may be rendered at a higher level of detail, so that, forexample, a shape or otherwise structural aspect may become visible. At astill further increased level of magnification, text of the retrieveddata within the rendered layout element may become legible.

Thus, it may be appreciated that the various level of detail thresholdsof the threshold manager 206 may be defined in terms of, e.g., pixels ofa current display screen, as obtained from the screen size monitor 204.For example, a particular data object may reach a first pixel sizecorresponding to a data level of detail threshold defined by the datathreshold manager 212, thus triggering retrieval of corresponding data.Upon further magnification, the data object may reach a second, largerpixel size, corresponding to a structural level of detail thresholddefined by the structural threshold manager 210, thereby triggeringinstantiation of responding structure of a corresponding layout templateselected by the template selector 214. Then, as magnification continues,the data object may reach a pixel size at which the rendering of thealready-retrieved data and already-instantiated structure may begin. Inthis regard, as referenced and detailed in examples below, the pixelsize of the various level of detail thresholds may be defined withrespect to portions or fractions of an individual pixel, since, forexample, it may be required to retrieve specified data at a time when arelated data object is currently too small to be rendered with an evensingle pixel of a current display screen.

In order to implement the various thresholds of the threshold manager206, an object size comparator 216 may be configured to perform theabove-referenced comparisons of a pixel size of a data object inquestion, relative to a corresponding current level of detail threshold.That is, as just referenced, the object size comparator 216 may beconfigured to compare a current size of a data object that is in theprocess of being magnified, relative to, e.g., a data threshold of thedata threshold manager 212. For example, at a point in time, a currentmagnification request may not yet have caused a data object to reach apixel size that meets or exceeds a pixel size defined by the datathreshold manager 212. However, as the magnification request continues,the pixel size of the requested data object will continue to grow, untilthe object size comparator 216 determines that the data threshold of thedata threshold manager 212 has been triggered. At this point, the objectsize comparator 216 may cause the visualization engine 102A to executean otherwise-conventional fetching of data required for the data objectbeing magnified from the database 104.

Similar comments would apply to operations of the object size comparator216 in comparing a current size of the data object being magnified withthe structural level of detail threshold of the threshold manager 210,and, thereafter, with respect to the visual level of detail threshold ofthe visual threshold manager 208. It may be appreciated that the objectsize comparator 216 may be configured to make such comparisons based onscreen size information obtained from the screen size monitor 204. Inthis regard, although the various level of detail thresholds referencedabove have been described with respect to a pixel size of thecorresponding display screen, other techniques may be used. For example,the object size comparator 216 may define comparisons with respect tolevel of detail thresholds that are defined in terms of a percentage ofavailable screen size. In any case, it may be appreciated thatoperations of the visualization engine 102A may translate easily fromvarious small screens, such as those available on smartphones or othermobile devices, all the way to large wall monitors or projections andbeyond, since the threshold manager 206 and the object size comparator216 are configured to operate based on whatever screen size is providedby the screen size monitor 204.

In the example of FIG. 2, the visualization engine 102A is illustratedas being executed using at least one computing device 218, whichincludes at least one processor 220 and computer readable storage medium222. That is, as described, the at least one computing device 218 mayrepresent virtually any suitable computing device, ranging from a mobiledevice to a desktop computer or workstation. As referenced above withrespect to FIG. 1, the at least one computing device 218 may representtwo or more computing devices, e.g., the server hardware 112 and/or theclient hardware 114. Meanwhile, the at least one processor 220 mayrepresent one or more processors operating alone or in parallel toprovide the various features and functions of the visualization engine102A as described herein. The computer readable storage medium 222 mayrepresent virtually any suitable non-transitory computer readablestorage medium that may be used to store instructions for the at leastone processor 220, and/or required data. That is, for example, thecomputer readable storage medium 222 may represent two or more storagemedia, such as a main memory used to implement the database 104, adisc-based hard drive, one or more cache memories, or any desired orsuitable arrangement of configured memory.

FIG. 3 is a flowchart 300 illustrating example operations of thevisualization engine 102 A of FIG. 2. In the example of FIG. 3,operations 302-312 are illustrated as separate, sequential operations.However, it may be appreciated that, in additional or alternativeimplementations, operations of the flowchart 300 may be executed in apartially or completely overlapping or parallel manner, or in a nested,iterative, looped, or branched fashion. Moreover, in variations of suchimplementations, additional or alternative operations or sub-operationsmay be included, and/or one or more operations may be omitted.

In the example of FIG. 3, a visual display of an object may be providedon a screen, the object being associated with object data having a datadisplay size smaller than a visual threshold and therefore not displayedon the screen (302). For example, the visualization engine 102A may beconfigured to provide a visualization of virtually any set of dataelements or data objects stored within the database 104. Variousspecific examples of such data are illustrated and described below, but,in general, it should be appreciated that such examples are intended asillustrative and non-limiting examples. Thus, by way of such example,the database 104 should be understood to include, e.g., customers of acustomer relationship management system, financial transactions executedby a business, data related to a manufacturing, shipping, or inventoryof items for sale, or virtually any other business or non-business datathat might be stored using the database 104.

Then, for example, when providing an initial visualization of such data,as referenced above, it may be impractical or impossible for thevisualization engine 102A to include visualizations of data objects thatare very small relative to higher levels of data objects and/or relativeto an available screen size. For example, in the context of a customerrelationship management database, the visualization engine 102A mayprovide a visualization, at a high level, of classes, groups, or othergroupings of customers, in which an individual customer record would betoo small to include when displaying a highest-available view of thecustomer database as a whole. Thus, with reference to the operation 302,such a customer record might correspond to the referenced object datahaving a data display size smaller than a visual threshold, andtherefore not displayed on the corresponding, current screen.

A magnification request to magnify the object at a magnification speedmay be received (304). For example, the request handler 202 may receivesuch a magnification request from the user of the system 100. Suchmagnification requests may be received in virtually any conventionalmanner. For example, the user interface 110 may be provided withcorresponding graphical controls for requesting magnification of adesignated area of a currently-rendered visualization. In relatedexamples, available human input devices and associated hardware may beused. For example, a mouse with a scroll wheel may be utilized to zoomin or out of the provided visualization. Associated techniques fordesignating a portion of a visualization to be magnified, and forrequesting the magnification, are generally known, and are therefore notdescribed herein in further detail, except as may be necessary orhelpful in understanding operations of the visualization engine 102A.

For purposes of understanding the operation 304, it may be appreciatedthat, in general, such magnification requests will be associated with acorresponding magnification speed. For example, the user may wish tozoom quickly from a customer-wide visualization of an entire customerdatabase, all the way to an individual customer data record. In otherexamples, the user may execute an initial magnification within one areaof a visualization of an entire customer database, determine thatdesired customer information is not likely to be included therein, andmay zoom back out to a level of the entire customer database, to therebyselect a different portion of the customer database for inspection. Inthe latter examples, magnification may occur at a more measured pace, asthe user attempts to determine whether further magnification andinspection will be useful. In various examples, such magnificationspeeds may be implemented by available hardware or software. Forexample, a scroll wheel of a mouse may be scrolled at a desired speed,which would then correspond to a corresponding magnification speed.Similarly, selection and continuous operation of a graphical control formagnification provided by the user interface 110 may be considered bythe request handler 202 to determine a current magnification speed.

A data threshold at which fetching of the object data must be initiatedto ensure receipt thereof prior to the visual threshold being reachedmay be determined (306). For example, the threshold manager 206 (e.g.,the data threshold manager 212), may determine a pixel size defining thedata threshold in serving as a trigger for initiating of a fetching ofthe associated object data.

Fetching of the object data may be initiated, based on the visualthreshold, the data threshold, and the magnification speed (308).Specific techniques for calculating the data threshold relative to thevisual threshold to ensure that the relevant object data is fetched intime for rendering thereof are described below, e.g., with respect toFIG. 9. However, in FIG. 3, it may be appreciated the object sizecomparator 216 may initiate the fetching of the relevant object datafrom the database 104 when a pixel size of the object meets or exceedsthe data threshold, relative to the visual threshold. In addition to themagnification speed as referenced in the operation 308, the object sizecomparator 218 may consider other useful factors, such as an averageround trip time required to request and retrieve the desired data fromthe database 104. In any case, as described herein, it may beappreciated that the use of the visual threshold and the data thresholdmay enable initiation of fetching of the required object data in time torender the object data seamlessly in the context of magnificationrequests of the user.

Finally in the example of FIG. 3, the object data may be displayedwithin the object upon magnification of the object meeting the visualthreshold (310). For example, the visualization engine 102A may causethe rendering engine 108 to display the relevant object data within theobject, in the context of the user interface 110. For example,individual customer information may be displayed within a customer dataobject.

Of course, it may be appreciated that FIG. 3 represents ahighly-simplified description of a basic example implementation ofconcepts underlying operations of the visualization engine 102A. Inparticular, for example, the simplified example of FIG. 3 does notexplicitly require or describe use of the structural level of detailthreshold described above with respect to corresponding layouttemplates. Of course, and as described in detail below, such structuralthresholds may be included in various implementations.

For example, in such implementations, as described above with respect toFIG. 2, the structural threshold may be used to trigger instantiation ofa corresponding layout template, once required data has been fetched andbecomes available for use in instantiation operations for thecorresponding layout template. In some implementations, however, suchinstantiation of corresponding layout templates may simply be executedin conjunction with triggering of the data threshold. In other words,for example, the data threshold may serve as both the data threshold andthe structural threshold, so that data is fetched and a correspondinglayout template is instantiated as soon as the data is available.

In the latter implementations, a marginal risk is incurred in that thecorresponding structure may be instantiated needlessly, such as when theuser decides to zoom out from a corresponding object prior to actualtriggering of the corresponding visual threshold, so that the data isretrieved and the corresponding structure is instantiated, even thoughrendering of the data and structure does not occur at that point intime. On the other hand, in scenarios in which data is frequentlyrequired to be displayed during zoom operations, it may be moreefficient to couple the instantiation of associated layout templateswith the data arrival, so that, for example, it is not necessary toinclude the structural threshold manager 210 (and execute operationsassociated therewith) as a separate element.

FIG. 4A is a block diagram of a visualization that might be provided bythe visualization engine 102A, illustrating a collection 402 of businesstransactions organized by individual business contact data objects 404.In other words, for example, the collection 402 may contain individualbusiness contacts, where any one such business contact may be associateda number of past, present/pending, or future business transactions. Inmore detail, for example, a business contact data object 404 isillustrated as including embedded elements 406, 412 at a lower level ofa hierarchy of the visualization 402. Similarly, data objects 408 and414 are embedded respectively within data objects 406, 412, and data410, 416 is included respectively within data elements 408, 414. Forexample, the data object 406 may illustrate a pending order for atransaction yet to be consummated, so that the data object 408 and data410 may represent, e.g., information describing a shipment or paymentrelated to the pending order. Meanwhile, the data object 412 mayrepresent a past order, so that the data object 414 represents a paidinvoice and the data 416 represents text of the paid invoice.

Meanwhile, FIG. 4B is a block diagram illustrating business transactiondata objects 418 in a visualization of transaction stages 420, 422, 424,426, and 428. Specifically, as shown, a data object 420 illustratesordered items, while the data object 422 illustrates shipped orders.Meanwhile, the data object 424 illustrates received orders, while thedata object 426 illustrates a stage in which invoices for orders havebeen paid, and the data object 428 represents a stage in which ordershave been cleared. As shown in FIG. 4B, the ordered stage data object420 may include a data object 430 embedded therein, which itself mayinclude an embedded data object 432. For example, the data object 430may represent an individual business contact, while the element 432illustrates a particular item that has been purchased/ordered.

Further, in FIG. 4C, a visualization of events timeline data objects 434is provided. As shown, a data object 436 illustrates a specific date atwhich various aspects of various business transactions occurred. Then,as also shown, a data object 438 may include various embedded dataobjects 444, with similar comments applying to a data object 440 and adata object 442 that includes data objects 446. It may be appreciatedthat the data objects 438, 440, 442 may be defined in a desired manner.For example, the data objects 438, 440, 442 may be representative ofindividual business contacts, any one of which may include, or beassociated with, various past, present, or future transactions asdiscussed above with respect to FIG. 4A. On the other hand, the dataobjects 438, 440, 442 may correspond more closely to individual stagesof FIG. 4B, irrespective of individual business contacts who might beincluded therein. In either case, as illustrated in FIG. 4C, theprovided events timeline provides a convenient visualization oftransaction information related to specific days.

More generally, the examples of FIGS. 4A, 4B, 4C illustrate, among otherfeatures, that the visualization engine 102 of FIG. 1 and thevisualization engine 102A of FIG. 2 may be configured to providevisualizations in a highly flexible and interactive manner. That is,FIGS. 4A-4C all provide visualization of, and access to, the same data,but from very different perspectives. In this regard, as described indetail below with respect to FIGS. 10-20, it may be appreciated that thedata objects of FIGS. 4A-4C may be considered to represent visualbundlers that are specifically configured to convey informationregarding groups or types of data objects, as well as informationregarding relationships between, or aggregations of, the various dataobjects.

In any case, regardless of a manner in which the data is visualized, thevisualization engine 102A, in conjunction with the above description ofFIGS. 1-3, may be understood to provide the user with an ability toutilize seamless zooming within the context of any such particularvisualization. For example, FIG. 5 is a block diagram of a magnifiedview of the paid data object 426 of FIG. 4B. A shown, the paid dataobject 426 includes a plurality of paid invoice data objects 502, suchas the individually-labeled invoice data objects 504.

Meanwhile, FIG. 6 illustrates a further-magnified view of the paidinvoice 504. As shown, FIG. 6 illustrates a purchase order data object602, as well as several other transaction documents associated with apaid invoice of the data object 504. Specifically, as shown, dataobjects 604, 606, 608 provide a visualization of individual dates andassociated transaction documents. As shown, the data object 604associated with the date 2014/03/13 and the data object 606 isassociated with the date 2014/03/11 illustrate transaction events thatoccurred on those dates, culminating with the payment occurring withinthe data object 604. Further, as shown in the further magnified view ofFIG. 7, which illustrates the data object 608 related to the date2014/03/10, further data objects for transaction documents associatedwith that date are illustrated. Specifically, as shown, the data object702 illustrates a delivery note, data object 704 illustrates a purchaseorder, and the data object 706 illustrates a sales order.

FIG. 8 is a block diagram of another example visualization that may beprovided by the visualization engine 102A of FIG. 2. Specifically, asshown, FIG. 8 illustrates a system landscape of data objects 802, whichmight represent, for example, an entire system landscape of anorganization. In the example of FIG. 8, a data object therefore may thusrepresent, e.g., a location, so that embedded data objects 806 mightrefer to individual workstations or other systems at that location.Conversely, in alternative examples, the data object 804 might representa particular type of system, so that the embedded data object 806 mightrepresent a location of the particular, corresponding system. In anycase, it may be appreciated from the above discussion of FIGS. 4A-7 thatthe same information may be visualized in a variety of differentmanners, and, in those context, information may be organized anddisplayed in a manner which facilitates a desired interaction on thepart of the user.

FIG. 9 is a flowchart 900 illustrating more detailed example operationsof the visualization engine 102A of FIG. 2. In the example of FIG. 9, arequest for a visualization of data may be received (902) from a user904. For example, the user 904 may be requesting an initialvisualization, to be used as a starting point for subsequent analysisand exploration of included data. By way of more specific example, theuser 904 may request the type of visualization illustrated in FIG. 4B,in which business data related to, e.g., customers and associatedbusiness transactions, is represented in the context of transactionstages associated with initiating and ultimately consummatingtransactions with the customers in question.

In this regard, it may be appreciated that the request from the user 904may be received by the request handler 202 by way of the user interface110. However, in the example, the illustration of FIG. 4B, as referencedabove, may be understood to represent an initial visualization, andtherefore not yet associated with a specific request for magnification.

Thus, in response to the request for the visualization, identified,corresponding data may be fetched (906). In conjunction therewith, anappropriate layout template may also be fetched (908). For example, thetemplate selector 214 of FIG. 2 may, based on the received request,access the template repository 106 in order to retrieve one or morelayout templates corresponding to the requested data and associated,requested visualization.

Thereafter, the visualization engine 102A may create the requestedvisualization (910). That is, as described, the created visualizationmay be rendered at a first, current level of magnification. At therequested or default size of the created visualization, thevisualization engine 102A must determine whether and to what extentincluded data and layout template structures should be fetched,instantiated, and/or rendered.

In more detail, the created visualization may be rendered at thecurrent, e.g., default, level (912) by the rendering engine 108. Forexample, in the example of FIG. 4B, the business transaction dataobjects 418 may represent an initial or default level of magnification.In FIG. 4B, for example, at a level of the business transaction dataobjects 418, the paid business transaction data object 426 may berendered in conjunction with remaining business transaction data objects420, 422, 424, and 428. In the example, the paid business transactiondata object 426 is associated with a layout template in the shape of acircle, having a certain color and being associated with static textindicating a title of “paid.”

As may be appreciated from the above description, the businesstransaction data object 426, derived from a corresponding layouttemplate as just referenced, may be associated with embedded layouttemplates and associated layout elements, which may thus be consideredto be children elements 502 of the data object 426, as illustrated anddescribed above with respect to FIG. 5.

Therefore, the visualization engine 102A may first determine anappropriate children size for an initial display of the children dataobjects 502 (914). That is, for example, in the example of FIG. 4B, theparent data object 426 is rendered at a certain, e.g., default, size, atwhich point it may occur that the thus-rendered data object 426 isassociated with some number of children data objects 502. In an exampleextreme case in which only a single child data object is included, thenthe single child data object may be associated with a maximum possiblesize thereof that may be displayed within a context of the already-sizedparent data object 426. In other examples, it may occur that a verylarge number of children data objects exist, in which case a size ofeach child data object may be determined to be very small. In an exampleimplementation, the business transaction data objects 418 may initially,by default, be assigned a maximum size possible when considering anavailable screen size and a requirement to include all of the businesstransaction data objects 418 and the initial rendering. In other exampleimplementations, however, a different default rendering size may beselected, or an initial rendering size of the business transaction dataobjects 418 may be flexibly or dynamically determined in conjunctionwith a number of children data objects to be included therein.

If a thus-determined child size of the children data objects isdetermined to meet or exceed a predefined visual level of detailthreshold (916) as may be determined by the visual threshold manager308, then rendering of the visualization may continue with a renderingof the corresponding children data objects (912). For example, in theexample of FIG. 4B, 16 children data objects 502 are present, and maythus be rendered within a context of the parent data object 426 asdescribed and illustrated above with respect to 4B, although a childsize of the children data objects may meet or exceed the visual level ofdetail threshold, so that individual children data objects may berendered, the child size may not sufficiently exceed the visual level ofdetail threshold to an extent necessary render legible text or otherfeatures therein. For example, the child size at the current level mayresult in individual child data objects being rendered as a single pixelwithin the parent data object 426. In examples where the child size issomewhat larger, the corresponding child data object may be rendered ata level that allows observation that text or other features areincluded, although not in a legible manner. Of course, at higher childsizes, corresponding children data objects may be rendered with includedtext and other features being completely legible.

Further, as may be observed from the operational loop between thedetermination of operation 916 and the rendering of operation 912,embedded levels of the visualization may be iteratively considered,until a level is reached at which a child size of that level does notexceed the visual level of detail threshold. In other words, forexample, a parent data object may have a first child which easilyexceeds the visual threshold, so that the child data object is rendered.The child data object may itself have a child (grandchild) data objectthat also exceeds the visual threshold, but to a lesser extent, and isthus rendered accordingly. Still further, the grandchild data object mayitself have a child (great grandchild) data object, which, a currentlevel of magnification, may fail to exceed the visual level of detailthreshold, as determined in the operation 916.

Once such a child size is reached that is below the visual level ofdetail threshold (916), a determination may be made as to whether thechild size of the child data object in question exceeds the structurallevel of detail threshold (918). In other words, for a child data objecthaving a child size that is just below the visual threshold, it maystill occur that the child data object has a size that exceeds thestructural level of detail threshold, thereby indicating a need tocreate corresponding child data objects (920), in anticipation of thepossibility of a subsequent magnification request causing the child sizeat the respective level to increase to a point of exceeding the visualthreshold.

Similarly, if the child size of the child data object is below thestructural threshold but above the data level of detail threshold (920),then corresponding child data may be fetched (920), along with acorresponding child template (926). Otherwise, if the child size isbelow the data threshold, there is no need to pre-fetch correspondingchild data at this point, so that rendering of the visualization may becompleted (928).

At this point in the operational flow of the flowchart 900, it may beappreciated that data objects above the visual threshold are includedwithin the completed rendering, along with all associated instantiatedlayout templates and included data, and rendered at whatever level oflegibility is possible for the determined rendering size. At one or morelevels immediately below the visual threshold, instantiated layouttemplates and associated data objects may be populated withpreviously-fetched data (i.e., data fetched during a previous iterationof the flowchart 900). Meanwhile, at one or more levels below thestructural threshold, data may be fetched, without having completedassociated instantiations of corresponding data objects. Finally, belowthe level of the data threshold, it is not necessary to take any furtheraction since it is assumed that during any subsequent zoom operations bythe user 904, there will be sufficient time to fetch appropriate dataand execute associated layout template instantiations, while dataobjects at higher levels are being rendered, and before a size of suchchildren data objects reaches the visual threshold.

Specifically, as shown, as the user 904 zooms in to the visualization(930), the zoom or magnification level is increased at a certainmagnification speed, so that the now-current magnification level ishigher with respect to the rendering of the visualization (912).Consequently, a children size of children data objects of parent dataobjects at the current (updated) magnification level may be determinedto be larger (914), so that associated children data objects may nowhave a child size which exceeds the visual level of detail threshold(916).

As may be appreciated, operations for populating and otherwise creatingchild objects at child sizes which exceed the structural threshold, ifany, may proceed (918, 920). Creation of such child objects may continueuntil a child size no longer exceeds the structural threshold. Then, atlower levels, child sizes exceeding the data level of detail thresholdmay trigger the fetching of associated data and templates (922, 924,926), which may continue until a currently-considered child size failsto exceed the data level of detail threshold, so that a rendering at thecurrent level of magnification may be completed (928).

By way of specific example, and with reference to FIGS. 4B and 5-7, itmay be appreciated that the business transaction data object 426represents a first level, while child transaction data objects 502represent a second level. Data objects 602-608 of FIG. 6 representchildren of the data object 504 at a third level, while, as describedabove, the data objects of FIG. 7 represent fourth level. Therefore,with reference to FIG. 9, in a particular implementation, it mayinitially occur that only the highest level data object 426 has a sizeabove the visual threshold, while the next-level data object 502 areabove the structural threshold right below the visual threshold, and thegrandchild data objects 602-608 are above the data threshold right belowthe structural threshold. Finally, in this example, the data objects atthe great grandchild level of FIG. 7 may be below the data threshold.

After one level of magnification, both the data object 426 and childdata objects 502 may exceed the visual threshold, while the grandchilddata objects 602-608 now exceed the structural threshold, and the greatgrandchild data objects at the level of FIG. 7 now exceed the datathreshold. If the data objects of FIG. 7 represent a lowest-availablelevel, then it may be appreciated that further zooming by the user 904may ultimately result in selected ones of the individual data objectsbeing displayed and rendered as being above the visual threshold.

Although not explicitly mentioned above, it may be appreciated from theillustrations of FIG. 4B and FIGS. 5-7 that, at higher levels ofmagnification parent and grandparent data objects may become too big tobe included within a display of a current display screen being used. Forexample, shown in FIG. 6, the data object 504 may be magnified to apoint that remaining ones of the data objects 502, or the original,parent data object 426 are no longer visible. Of course, in response tozooming out by the user 904, corresponding operations of the flowchart900, in pertinent part, may be reversed. Consequently, for example,higher level data objects previously-sized out of the rendering may beincluded again, and data previously-fetched for relatively low leveldata objects may be released to the database 104. Of course, a manner intiming of such release of previously-fetched data may depend on variousfactors, such as an extent of available memory, including local caches.

In a specific example implementation of FIG. 9, it may occur that thevisual threshold for a particular detail to be rendered is 20 pixels,while a time for creating (rendering) the detail might be 10 ms.Meanwhile, an average round trip retrieval time for fetching associateddata may be 200 ms, while zooming by a factor of 10 takes 500 ms.

Since zooming occurs exponentially, the formula for a magnificationfactor M over time t may be expressed as M(t)=f^((t)). Therefore, in theexample just referenced, with a factor of 10 and 500 ms, the aboveformula yields f=10^((1/500))=1.0046, so that in the 10 ms for adetailed creation, the size increases to 1.0046¹⁰=1.047 of the originalsize, i.e., the object is about 5% bigger. Consequently, creation of thedesired visual details should begin at a size of about 95% of the visualthreshold, which, in the example, would be 19 pixels.

Further, during the 200 ms of the round trip, the size increases tof²⁰⁰=2.511 of the original size. So in order to have the desired dataavailable when the object is 19 pixels wide, the data should berequested when the object is about 19/2.511=7.5 pixels wide, so that 7.5pixels may be observed to be the data threshold.

Thus, in summary, the examples of FIGS. 2-9 illustrate that when avisual data object is newly created or rendered at a particular zoomlevel, a corresponding actual screen size may be calculated and comparedwith the various thresholds. If the visual object is larger than thedata threshold and the data is not yet cached locally, the data shouldbe requested. If the visual object is larger than the structuralthreshold and the detail objects are not yet created, then instantiationmay proceed according to metadata of respected layout elements. Finally,if the visual object is larger than the visual threshold, then renderingof the visual object (using data and structure previously determined atprevious zoom levels) may proceed.

Various other implementations may include additional or alternativefeatures. For example, automatic zooming on a selected element may besupported by, e.g., evaluating, the various level of detail thresholdsfor a final or highest-available level of magnification, before zoomingoperations actually begin. In the final magnification level, adjacentvisual objects of the selected data objects may be visible but small,and may be outside a visible area of a current display screen. In suchscenarios, fetching of data and creation of structural element detailsmay be suppressed, since the details would only be visible in aperipheral screen area, if at all.

Further, in additional or alternative implementations, it may occur thata particular magnification level includes a very large number of dataobjects. As zooming occurs, such data objects may increase in size, andmay get closer and closer to reaching the visual threshold. The resultmay be a simultaneous creation of a large number of visual data objects,which might result in an undesired slowdown of the zooming process, oran undesired increase in processor load. In order to avoid suchscenarios, the visualization engine 102A may preemptively begin arendering process, and related processes, prior to the time that wouldotherwise be necessary according to the description of FIG. 9, above.

For example, rendering of a portion or percentage of the large number ofdata objects that might potentially be required to be createdsimultaneously may be executed preemptively. Of course, such operationsrun a risk that some or all of the rendering operations executedpreemptively may not ultimately be necessary or required. For example,the visualization engine 102A may begin a rendering process for apercentage of data objects prior to visual threshold being reached, andthe user 904 may elect to stop current zooming operations prior to everreaching the corresponding visual threshold.

Nonetheless, in certain scenarios, it may be advantageous to execute thetype of preemptive rendering just referenced. In a specific example, ifa structural threshold is considered to be S pixels, then the structuralthreshold manager 210 and the object size comparator 216 may ensure thatthe corresponding objects are created when the corresponding objectswould be S pixel large, where S may typically represent 1 pixel.Meanwhile, the data threshold may be represented as D pixels, so thatthe data threshold manager 212 and the object size comparator 216 maycause corresponding data to be requested when the object in questionwould be D pixels large, e.g., approximately 0.2 pixels. Then, in theexample, a child object may be created when the corresponding data isavailable, and in accordance with a determination that a calculatedrandom number between 0 and 1 is less than or equal to a value of aprobability function P(CS), where CS represents a child size in pixelsat a current zoom level.

In the example, this probability function is equal to 1 if CS is lessthan or equal to S, and the probability function may be chosen so thatits value is less than or equal to 0 for CS<D. That is, if the size isso small that the data is not yet requested, then a probability that thechild would be created will be 0. On the other hand, a value for CS=Swould be equal to 1, because a probability of creation should be 100%when the size of the object reaches the structural threshold.

In a more particular example, a linear function may be written asP=(CS−D)/(S−D). In another example, a quadratic function, which willcreate fewer objects at lower sizes, would be 1−(S−CS)²/(S−D)². Ofcourse, such probability functions are provided merely by way ofexample, and other types of functions may be used. For example, adiscontinuous function may be used which has a constant value (e.g.,P=0.2) for D<CS<D, 0 for CS<D, and 1 for CS greater than or equal to S.

FIG. 10 is a block diagram illustrating a visualization engine 102Brepresenting a second example embodiment of the visualization engine 102of FIG. 1. As described in detail below, the visualization engine 102Bmay be configured to render very large sets of visual data objects in away that visually conveys the meaning or other aspect of the data.Moreover, the resulting visualizations may be based on grouping criteriaand layout templates, so that, as opposed to conventional, hard-codedvisualizations, the visualizations of the visualization engine 102B maybe created, transformed, or nested by the user.

In some example embodiments, the visualization engine 102B may beimplemented in conjunction with features and functions of thevisualization engine 102A of FIG. 2. In other words, the visualizationengine 102 of FIG. 1 may be understood to represent some or all ofeither or both of the visualization engines 102A, 102B. In fact, many ofthe visualizations of the example visualizations of FIGS. 4A-8 may beimplemented using features and functions of the visualization engine102B. For the sake of clarity in the following description, the variousexample visualizations of FIGS. 12A-19 are primarily described withrespect to features and functions of the visualization engine 102B.Nonetheless, as described where appropriate in the below description,and as just referenced, it should be appreciated that the visualizationengines 102A, 102B may be used together synergistically to provide adesired experience for the user of the system 100 of FIG. 1.

In the example of FIG. 10, the visualization engine 102B includes arequest handler 1002. As already described with respect to the requesthandler 202 of FIG. 2, the request handler 1002 may be configured toreceive requests from a user, by way of the user interface 110. In thecase of the visualization engine 102B, as described in detail below, therequest handler 1002 may be configured to receive requests from the userfor defining, characterizing, and displaying groups of data in a desiredmanner, and for subsequently regrouping or recursively regrouping thedata in a manner which allows the user to interact with the data in anefficient, intuitive manner.

More particularly, a property filter 1004 may be configured to receive,by way of the request handler 1002, a desired or specified property thatis common to groups of data stored within the database 104. Inconjunction with operations of the property filter 1004, a templateselector 1006 may be configured to utilize grouping criterion 1008 toselect one or more appropriate layout templates from the templaterepository 106 of FIG. 1. In this way, a set of visual objects may bedivided into subsets according to specified properties that all elementsin each subset have in common. Then, each of these subsets may be putinto a visual bundler, which is generated based on a specified layouttemplate that is selected by the template selector 1006, based on thegrouping criterion 1008.

Additionally, a layout engine 1010 may be configured to calculate orotherwise determine a position, size, or other characteristic of theresulting visual bundlers, depending on data associated therewith. As aresult, the visual bundlers provided by the visualization engine 102Bmay be arranged meaningfully with respect to one another, and may beprovided with a relative size or other visual characteristic thatconveys information to the user with respect to the data included withineach visual bundler, or with respect to relationships between the dataand/or the bundlers.

Finally in the example of FIG. 10, the visualization engine 102B isillustrated as including an aggregator 1012. As described in detailbelow, the aggregator 1012 may be configured to aggregate valuesincluded within each visual bundler. Such aggregation may include, forexample, summations, averages, minimum/maximum values, or virtually anyappropriate or available calculation or other interpretation of valuesor other data included within the visual bundler.

Thus, the user may change any of the current grouping criterion, bundlerlayout, or bundler arrangement during runtime of a visualization.Afterwards, the visual data objects may immediately change, dissolve andre-form, or otherwise rearrange themselves to match the user's changes,in a smooth animation.

FIG. 11 is a flowchart 1100 illustrating example operations 1102-1110 ofthe visualization engine 102B of FIG. 10. As with FIG. 3, above, it willbe appreciated that, although the operations 1102-1110 are illustratedas separate, sequential operations, any two or more of the operationsmay be executed in a partially or completely overlapping and parallelmanner, or in a nested, iterative, looped, or branched manner. Moreover,in various implementations, additional or alternative operations orsub-operations may be included, and/or one or more operations may beomitted.

The following description of the example of FIG. 11 is provided withrespect to FIGS. 12A, 12B, 12C, for the sake of illustration. It will beappreciated that such examples are illustrative and non-limiting, andvarious other examples are provided below with respect to FIGS. 13-19,while FIG. 20 provides an example of a more detailed operational flow ofthe visualization engine 102B.

In the example of FIG. 11, a request for a visualization of a pluralityof data elements may be received, the request including a commonproperty (1102). For example, the request handler 1002 of FIG. 10 mayreceive a request from a user for the visualization of data elementsrepresenting specified computing elements and resources within a systemlandscape of an enterprise or other entity. For example, as shown inFIG. 12A, a common property may represent a city or other locationinformation associated with computing resources located therein, so thatthe city represents the common property referenced above. In FIG. 12A, avisual representation of the United States 1202 is illustrated withreference to the cities Philadelphia and Palo Alto, where it is assumedthat the user has requested visualizations of computing resources withina system landscape of a national enterprise, including resources in theidentified cities.

The plurality of data elements may be filtered based on the commonproperty, to obtain data subsets (1104). For example, the propertyfilter 1004 of FIG. 10 may be configured to filter data elements basedon included values within a column or other field that is designated asproviding a name of a city associated with a particular computingresource. For example, with reference to FIG. 1, it may occur that thedatabase 104 has a complete listing of all computing resources of thenational enterprise in question, where each computing resource is storedwithin the database 104 in a format that includes a city of location ofeach corresponding computing resource. Then, an appropriate query may beexecuted against the database 104, in order to obtain all relevantcomputing resources whereupon the property filter 1004 may filter thequery results so as to identify individual data elements with acorresponding city of location.

A grouping criterion linking the common property with at least onelayout template providing a geometric representation of the commonproperty may be accessed (1106). For example, the template selector 1006may access the grouping criterion 1008 to determine an appropriategeometric representation. In the example of FIG. 12A, a geometricrepresentation includes the outline of the United States 1202, alongwith geometric shapes (e.g., circles) 1204 (representing the city ofPhiladelphia) and the circle 1206 (representing the city Palo Alto).

Based on the at least one layout template, a plurality of visualbundlers may be generated, each visual bundler corresponding to a datasubset of the data subsets (1108). For example, the layout engine 1010may be configured to generate the actual visualization of FIG. 12A,according to the selected templates and data subsets. In other words, itmay be appreciated that the layout templates of the template repository106 represent, by themselves, otherwise generic geometric representationand associated visualization options or other details.

For example, the template repository 106 may include templates forcountries, such as the United States, as well as templates specifyingcircular shapes having specific optional/selectable characteristics,such as size, color, or associated text. Thus, in operation, the layoutengine 1010 may be configured to combine these generic layout templateswith actual data requested and provided by way of the request handler1002 and the property filter 1004, to thereby instantiate an actual,desired visualization, such as the visualization of FIG. 12A.

That is, for example, the example of FIG. 12A illustrates thevisualization of the United States 1202, along with specific visualbundlers 1204 and 1206 representing, respectively, Philadelphia and PaloAlto. Moreover, as shown, each of the visual bundlers 1204, 1206 includecorresponding data elements of the defined data subsets, such as thevisual data objects 1208 of the visual bundler 1204. The underlying,selected layout templates may provide options, such as optional sizes,colors, shapes, and included text, all of which represent potentialoptions for the visualization of FIG. 12A. In a specific instance,however, the resulting visualization may be executed in a desired orspecified manner. For example, the included visual bundlers would ofcourse correspond to actual cities of location of interest of thenational enterprise in question, and visual bundlers having differentcharacteristics may be predefined or specified in a desired manner,e.g., different colors or shapes may be utilized to visualize the dataobject 1208 included within the visual bundler 1204. Moreover, specific,detailed information that is specific to an actual visualization beingcreated may be included, such as a designation within the visual bundler1206 that three of the computing resources included therein areconsidered to be in a critical condition.

Finally with respect to the example of FIG. 11, the visual bundlers,each illustrating its corresponding data subset, may be displayed, tothereby provide the visualization in the manner that conveys the commonproperty and a relationship of the data subsets to one another in thecontext of the common property (1110). For example, the layout engine1010 may be configured to display the visual bundlers 1204, 1206, eachillustrating its corresponding data subset of computing resourceslocated at the corresponding city, and within the visualization of theUnited States 1202. This way, as just referenced with respect to theoperation 1110 of FIG. 11, the visualization of FIG. 12A may be providedin a manner that conveys that, for example, the common property of thedata objects 1208 is geographical presence at a Philadelphia location,while a relationship of the data object representing Philadelphia andassociated to the visual bundler 1206 provides further information forrendering the bundler (i.e., a relationship of the city in questionwithin the United States).

In more detail with respect to the examples of FIG. 12A, 12B, 12C, asdescribed above, the visualization of the FIG. 12A provides a birds-eyeview of technical centers in city-specific data centers. Once providedwith this visualization, the user may immediately be made aware of, forexample, locations of relevant data centers, as well as which technicalsystems are included therein, and associated information such as acritical condition or other status of individual technical systems.

In the example of FIG. 12B, the visual bundler 1204 is illustrated asbeing magnified, so that an individual data object 1210 of the dataobjects 1208 may become more visible. Thus, as illustrated in theexample of FIG. 12C, the visual data object 1210 may be magnified to apoint that specific information regarding technical resources becomevisible. Of course, it will be appreciated that the magnification may beexecuted utilizing the techniques described above with respect to FIGS.1-9. However, other techniques may also be used. For example, uponselection of the visual bundler 1204 by the user, the layout engine 1010may be configured to dissolve or otherwise remove other elements oraspects of the visualization of FIG. 12A, while thereafter rendering thevisual bundler 1204 at a requested size. Similar, this would apply tooptions for zooming into the data object 1210, as opposed to, e.g.,dissolving the visual bundler 1204 and remaining ones of the data object1208, in order to provide the visualization of the data object 1210 ofFIG. 12C.

FIG. 13 provides another example visualization that may be generated bythe visualization engine 102B of FIG. 10. As shown, the example of FIG.13 illustrates a visualization in which visual bundlers correspond toindividual countries. For example, a visual bundler 1302 representsGermany, while included visual data objects 1304 represent currentprojects being undertaken by a business with customers or potentialcustomers in Germany. Meanwhile, as shown, a visual bundler 1306represents France, and included current projects being conducted there,although, as shown, individual data objects are not illustrated withinthe visual bundler 1306, for example, because no such current projectsmay exist, or, because a very large number of current projects exist andare therefore too numerous to be included individually within the visualbundler 1306.

Again with reference to the techniques of FIGS. 1-9, it may beappreciated that subsequent zooming on the visual bundler 1306 mayresult in a magnification of desired subsets of current projects inFrance to a visual/legible size. In additional or alternativeimplementations, the visual bundler 1306 may itself be resized larger,in order to individually display current projects that would be includedtherein. Similar comments apply to other visual objects within FIG. 13(e.g., a visual bundler 1308 representing current projects in Poland, avisual bundler 1310 represent current projects in Switzerland, visualbundler 1312, representing projects in Italy, visual bundler 1314,representing current projects in Spain, and visual bundler 1316,representing current projects in Denmark).

In the example of FIG. 13, as may be appreciated from the above exampleof FIG. 12A, these various visual bundlers may optionally be created andvisualized as a shape outline of a corresponding country. Further in theexample of FIG. 13, the current projects represented by the data objects1304 of the visual bundler 1302 are illustrated as individual visualblocks, each representing a current project. In example implementations,upon selection of the visual bundler 1302, the user may be provided withan option and ability to display the current projects represented by thedata objects 1304 in a different desired manner.

For example, in the example of FIG. 14, current projects are illustratedby stages 1402-1414. Specifically, as shown, a visual bundler 1402corresponds to a bidding stage, a visual bundler 1404 corresponds to acontract sign stage, a visual bundler 1406 corresponds to a constructionplan stage, while a visual bundler 1408 corresponds to a startproduction stage. Further, a visual bundler 1410 corresponds to ashipment stage, a visual bundler 1412 corresponds to a constructionstage, and a visual bundler 1414 corresponds to a startup stage.

Thus, as may be appreciated, the user may quickly and easily determinewhich projects are in which project stage. For example, the user maynotice that a relatively large number of current projects are in thevisual bundler 1412 representing construction stage, and may investigatethe construction stage in order to verify that no difficulties arepresent which might contribute to the construction stage representing abottleneck in the overall advancement of current projects through thevarious stages of FIG. 14.

FIG. 15 provides an example visualization corresponding generally to theexample visualization of FIG. 4B, and therefore not described here indetail. Instead, FIG. 15 is intended to illustrate a visual bundler1502, which may represent, or correspond to, the visual data object 426of FIG. 4B. That is to say, the visual data object 426 of FIG. 4B may beunderstood to be constructed using the visual bundler techniquesdescribed above with respect to FIGS. 10 and 11. Conversely, the visualbundler 1502 of FIG. 15 may or may not utilize the magnification andzooming techniques described above with respect to FIGS. 4B, 5, 6 and 7.

For example, as shown in FIG. 16, visual data objects 1602 generallycorrespond to the visual data objects 502 of FIG. 5. However, the dataobject 1602 need not necessarily be obtained for viewing through themagnification and zooming techniques described above with respect toFIGS. 4B and 5. Instead, for example, as referenced above, thevisualization of FIG. 15 may be dissolved, so that all other visual dataobjects of FIG. 15 disappear, while the visual data objects 1602 withinthe paid stage are automatically distributed evenly over an availableviewing area.

FIG. 17-19 illustrate an example of nested visual bundlers. In theexample of FIG. 17, a visual bundler 1702 illustrates a monitoringbundler associated with monitoring operations of an example computersystem. On the highest level within the visual bundler 1702, theincluded system events are grouped by event type, wherein a visualbundler 1704 corresponds to events associated with changes to users,while a visual bundler 1706 include all other events.

Thus, for example, zooming in on the other event bundler 1706 mightshow, for example, bundlers for different interaction types, such as“download” or “field content change.” Meanwhile, within the visualbundler 1704, various visual data objects 1708 represent system eventsassociated with changes made to individual user accounts. FIG. 18illustrates a magnified view of the visual data objects 1708 associatedwith changes to users. As shown, many different such user changes may beincluded, e.g., a creation or deletion of a user, profile, or role, or achange or status of a password, alias, or group. Specifically, thevisual bundler 1802 corresponds to user profiles that have been added.

Consequently, when these visual data objects 1802 associated with anadded profile are provided in the example visualization of FIG. 19, anindividual visual bundler 1902 may be provided which is at a level of aspecific user associated with the added profile. Thus, as may beappreciated, the examples of FIGS. 17-19 illustrate that the describednesting of visual bundlers essentially realizes a geometric equivalentof a dynamically-generated search tree. That is, as shown and described,a structure for executing a search for a desired data element (e.g., asearch for the specific user profile added and associated with thevisual bundler 1902) is not required to be fixed or otherwisepredefined. Consequently, during a runtime of providing visualizationsof FIGS. 17-19, multiple alternative search trees may be created for thesame underlying content, with minimal effort, and in a manner which ishighly intuitive and useful for the user. For example, the geometricnature of the illustrated nested bundlers implies that the user mayreceive a distribution of content over bundlers, without having tomanually open/close any folder or node.

In a similar example, not specifically illustrated, a visual bundler forlogging on to a system may include embedded bundlers corresponding todifferent terminal identifiers. Then, for a particular terminalidentifier, a third level of bundlers may be included, which representdifferent timestamps. Thus, at the final embedded level, the user may beprovided with subsets of logon events that occurred at a specific time,and from a specific terminal.

In a different context, e.g., a medical context, cases for thousands ofpatients may be grouped by diagnoses. Then, even for a large number ofdifferent subgroups corresponding to different diagnosis, the user mayimmediately visualize which subgroups/diagnoses contain a large numberof patients, and which contain relatively few patients. Moreover, eachpatient may be associated with a visual coding to correspond to anaspect of the diagnosis, such as, e.g., a level of prognosiscorresponding to a range of possible medical outcomes.

FIG. 20 is a flowchart 2000 illustrating more detailed operations of thevisualization engine 102B of FIG. 10. In the example of FIG. 20, arequest may be received (2002) from a user (2004). In the example, therequest may immediately be applied against the database 104, so thatrecords representing query results may be received therefrom (2006).

The user 2004 may then select a desired grouping mode (2008). Variousexample of such grouping modes are provided, or would otherwise beapparent. Once the grouping mode has been selected, the retrieved datarecords may be subdivided in groups accordingly (2010). At the sametime, a corresponding, appropriate bundler layout template may beselected (2012). Consequently, as described, a bundler for each groupmay be created (2014), using the selected template. Rendering of thethus-grouped members within a corresponding bundler may then be executed(2016).

If the user 2004 selects a particular subgroup from a particular bundler(2018), then recursive grouping may be implemented. That is, as shown,the user 2004 may select a new or different grouping mode (2008), thusultimately resulting in a corresponding rendering of included groupmembers within the newly-created visual bundler.

In this way, for example, the user 2004 may create visual bundlersincluding data subsets grouped according to a common property. Then, theuser 2004 may create embedded visual bundlers within the visualbundlers, in which each data subset is grouped according to a secondcommon property. Afterwards, the user 2004 may instead re-group the datasubset of each visual bundler according to a third common property, inplace of the second common property. Or, the user 2004 may createfurther-embedded visual bundlers within the embedded visual bundlers.

To provide further additional examples related to such recursivegrouping, for example, it may occur that, in the example of FIG. 12A,the user initially elects to group technical systems based on city oflocation of an underlying data center. Thereafter, however, the user2004 may select one such resulting visual bundler (e.g., the visualbundler 1204 of FIG. 12A, and may thereafter group the included dataobjects 1208 according to some other grouping criteria (commonproperty). For example, the data objects 1208 may be grouped accordingto a current status of each of the underlying technical systems. In thisway, for example, the user 2004 may easily perform an iterative,recursive, dynamic search, in a visual and intuitive manner. Forexample, the user 2004 may, in the manner just described, easily locatea particular technical system within a Philadelphia data center that hascontributed to an exception in operations of the IT landscape.

Optionally, as shown, following a rendering of group members within abundler (2016), the user 2004 may be provided with an option to change acurrent grouping mode (2020). In this case, the group members of thevarious current bundlers may be collected, while the current bundlersare destroyed (2022). Thereafter, the new grouping mode is implemented,including subdividing the existing records in new groups, according tothe new grouping mode. In other words, the user 2004 may regroup thedata elements according to a second common property to get a secondplurality of visual bundlers, using second geometric shapes to conveythe common property and the relationships between the data elements andbetween the visual bundlers.

For example, in the example of FIG. 12A, the user may wish to completelyremove the visualization based on city of location within the UnitedStates, and may instead, for example, group all technical systemsaccording to some other grouping criterion. For example, the user 2004may specify grouping of all technical systems according to a currentstatus, regardless of location, or according to some other criterion,such as current operating system, or most recent crash or othermalfunction.

In order to implement the various features and functions described, thelayout templates of the template repository 106 may be soft-coded. Forexample, the following pseudo code represents an example soft-coding fora visual bundler.

Pseudo Code 1 { “ID”: “processbundler”, “style”: “default”,“aspect-ratio”: 1.6, “elements”: [ { “element”: “shape”, “id”:“background”, “contour”: “arrow”, “color”: “FFAFCF70”, “plasticity”: 12}, { “element”: “label”, “id”: “caption”, “y”: “1%w”, “x”: “5%w”,“width”: “82%w”, “height”: “12%w”, “format”: { “text-align”: “center”,“font”: “Verdana”, “font-weight”: “bold”, “letter-spacing”: 1, “color”:“FF505050” }, “line-aspectratio”: 8, “content”: “$core:name” }, {“element”: “set”, “id”: “children”, “contour”: “rectangle”, “x”: “18%w”,“y”: “22%h”, “width”: “66%w”, “height”: “70%h”, “content”: “$children” }] }

As shown in pseudo code 1, elements of the visual bundler may bedefined, such as a shape, background, contour, color, and plasticity.Further, a static label or caption may be included, along withspecifications for a size and positioning thereof. Associated formattingand content may be specified. Further, children of the visual bundlermay similarly be specified. As shown, children elements also may bespecified according to contour and content.

As described above, the aggregator 1012 of FIG. 10 may be configured toprovide aggregations for specified bundlers. For example, a bundlergrouping a specific type of financial transaction may be operated on bythe aggregator 1012 to obtain a total monetary value of the bundledfinancial transactions.

More generally, every time a bundler is grouped, the aggregator 1012 maycreate an aggregation object for each bundler or bundler subgroup. Therequired aggregations may be determined from the grouping information inthe selected bundler layout template, and may be evaluated anddynamically assigned to the corresponding aggregation object. Then, thealgorithms arranging the visual bundlers, i.e., as described above withrespect to the layout engine 1010, may access the aggregation objectsfor use in conjunction with layout algorithms translating the selectedbundler layout template into the requested instantiated visualization.As a result, aggregated values may easily and prominently be displayedin conjunction with each visual bundler. As referenced above,aggregation bodies may include, e.g., NIN(minimum), MAX(maximum),AVG(average), COUNT, and SUM. These and other aggregation values may beapplied to any appropriate attribute of the objects contained in thesubset of a visual bundler in question.

By way of more specific example of the type of algorithm referencedabove for creating the subgroups of a set of visual bundlers, thefollowing algorithm may be used. For example, for all items in a set tobe subdivided, the grouping property may be evaluated. Then, for eachoccurring property value, an unambiguous, alphanumeric key may becalculated (e.g., using an appropriate hash function).

The resulting key may be used as a signature of the correspondingsubgroup. Then, all such subgroups may be stored in a dictionary datastructure configured to associate the signature with the correspondingsubgroup. Consequently, if the dictionary data structure contains theproperty signature of an object as a key, this object will be assignedto the corresponding group. If the key is not contained in thedictionary, however, a new subgroup for the respective signature may begenerated and stored in the dictionary.

As a result, in this example, when a bundler is created for eachsubgroup (i.e., for each distinct attribute value), the data objectsassigned to this subgroup will be removed from the original set andarranged within the contour of the visual bundler. If an item occurs inseveral subgroups, the item may be replicated so there is one copy ineach of the corresponding visual bundlers.

Thus, the systems and methods described above provide for a very fastand flexible exploration of very large datasets. The user feels incontrol due to the perception that all desired content is visible, andthat it is possible to drill down, inspect, group, select, and arrangecontent arbitrarily in the course of exploring and investigatingspecific questions.

Moreover, no context changes between aggregated views and analysis onindividual object levels may be perceived. Further, the visuallyexpressive groupings provided by the visual bundler described hereinensure that a user is not overwhelmed by flat sets of hundreds ofthousands of objects, but rather sees the higher level structures in abirds-eye view, and in finer detail while zooming in. Moreover, asdescribed, a multi-level zooming is possible. Consequently, if the userrepeatedly groups a set of data objects, drills down into a subsetthereof, and then groups the subset again, the context of the precedingsteps is not lost, but rather is preserved in the visual structure ofthe higher zoom levels.

Implementations of the various techniques described herein may beimplemented in digital electronic circuitry, or in computer hardware,firmware, software, or in combinations of them. Implementations may beimplemented as a computer program product, i.e., a computer programtangibly embodied in an information carrier, e.g., in a machine-readablestorage device or in a propagated signal, for execution by, or tocontrol the operation of, data processing apparatus, e.g., aprogrammable processor, a computer, or multiple computers.

A computer program can be deployedto be executed on one computer or on multiple computers at one site ordistributed across multiple sites and interconnected by a communicationnetwork.

Method steps may be performed by one or more programmable processorsexecuting a computer program to perform functions by operating on inputdata and generating output. Method steps also may be performed by, andan apparatus may be implemented as, special purpose logic circuitry,e.g., an FPGA (field programmable gate array) or an ASIC(application-specific integrated circuit).

The processor and the memory may be supplemented by, orincorporated in, special purpose logic circuitry.

To provide for interaction with a user, implementations may beimplemented on a computer having a display device, e.g., a cathode raytube (CRT) or liquid crystal display (LCD) monitor, for displayinginformation to the user and a keyboard and a pointing device, e.g., amouse or a trackball, by which the user can provide input to thecomputer. Other kinds of devices can be used to provide for interactionwith a user as well; for example, feedback provided to the user can beany form of sensory feedback, e.g., visual feedback, auditory feedback,or tactile feedback; and input from the user can be received in anyform, including acoustic, speech, or tactile input.

Implementations may be implemented in a computing system that includes aback-end component, e.g., as a data server, or that includes amiddleware component, e.g., an application server, or that includes afront-end component, e.g., a client computer having a graphical userinterface or a Web browser through which a user can interact with animplementation, or any combination of such back-end, middleware, orfront-end components. Components may be interconnected by any form ormedium of digital data communication, e.g., a communication network.Examples of communication networks include a local area network (LAN)and a wide area network (WAN), e.g., the Internet.
